Shown in Figure 12 (B), shell main body 133 comprises: the first terminal maintaining part 111b that keeps the first terminal 143a, the 144a of relaying terminal 143,144; The second terminal maintaining part 111c that keeps the second terminal 143b, the 144b of relaying terminal 143,144; And variant part 112.Variant part 112 is arranged between the first terminal maintaining part 111b and the second terminal maintaining part 111c, is used for to the direction strain that shortens the distance between the first terminal maintaining part 111b and the second terminal maintaining part 111c.
Because such variant part 112 is set, thereby, when when container body 105 is installed liquid detecting unit 111, can the first terminal maintaining part 111b of liquid detecting unit 111 be out of shape to the second terminal maintaining part 111c, one side by variant part 112.Therefore, can under the first terminal 143a, the 144a of the relaying terminal 143,144 that keeps by the first terminal maintaining part 111b and situation that container body 105 does not conflict, install.In addition, owing to be out of shape by strain, thereby return on the origin-location at the first terminal maintaining part 111b after the installation.Therefore, the first terminal 143a, the 144a of relaying terminal 143,144 can be connected on the terminal of container body 105 reliably.Thereby, can prevent that breakage takes place relaying terminal 143,144 when container body 105 is installed liquid detecting unit 111, can realize reliable conducting.
In addition, if the first terminal 143a, the 144a of relaying terminal 143,144 with situation that container body 105 contacts under be mounted, then because poor flow takes place sometimes in distortion, present embodiment can be avoided this problem reliably.And, when dismounting liquid detecting unit 111,, can easily disassemble if variant part 112 distortion are dismantled.As further effect, when when liquid detecting unit 111 has applied impact,, can absorb the impact of self transmitting to liquid detecting unit 111 owing to there is variant part 112, be difficult to transmit thereby impact to sensor element (piezoelectric element).
Do not limit especially for the first terminal maintaining part 111b and the second terminal maintaining part 111c, as long as can keep relaying terminal 143,144.Shown in Figure 12 (B), the second terminal maintaining part 111c forms the boss shape.For the second terminal 143b and sensor element 132 shown in Figure 10 are kept in touch, on relaying terminal 143,144, formed hole 161 as shown in figure 10.In this hole 161, be pressed into the second terminal maintaining part 111c of boss shape.
On the other hand, the first terminal 143a, 144a preferably remain on the first terminal maintaining part 111b movably.For this reason, shown in the Figure 14 (B) shown in the A portion of Figure 14 (A) is amplified, on the first terminal 143a, the 144a of Figure 14 (A), be formed with the 143a1 of slotted hole portion, 144a1.The first terminal maintaining part 111b that forms jut inserts the logical 143a1 of this slotted hole portion, 144a1.So, the first terminal maintaining part 111b keeps the first terminal 143a, the 144a of relaying terminal 143,144 movably.
In addition, the first terminal 143a, the 144a of relaying terminal 143,144 to the direction of variant part 112 strains, be that the direction of arrow of Figure 14 (B) is highlighted configuration, and kept by the first terminal maintaining part 111b.The length direction of the 143a1 of slotted hole portion, the 144a1 of the first terminal 143a, 144a is with consistent in the direction of arrow of outstanding biased direction shown in Figure 14 (B).
As Fig. 6 (B) and shown in Figure 11, the variant part 112 of cell enclosure main body 133a comprises movable body 112c, supports the support 112b of movable body 112c and the connecting portion 112d that connects movable body 112c and support 112b.The direction that relay 143c, the 144c of movable body 112c and relaying terminal 143,144 extends is arranged on the first terminal maintaining part 111b one side across.The direction that relay 143c, the 144c of support 112b and relaying terminal 143,144 extends is arranged on the second terminal maintaining part 111c, one side across, and is arranged with movable body 112c branch.In addition, stipulated slit 112e by movable body 112c, support 112b and connecting portion 112d.Variant part 112 can be by the mode strain of the groove width W that dwindles this slit 112e.
Shown in Figure 12 (A), the first terminal maintaining part 111b is comprised in free end one side of extending from the cardinal extremity with connecting portion 112 bindings among the movable body 112c.And the zone that forms the first terminal maintaining part 111b is outstanding, thereby brings into play function as applying the operating portion 111b1 of external force to variant part 112.
Relaying terminal 143,144 is formed by metal thin plate.As Figure 10 and shown in Figure 11, relay 143c, 144c comprise: the first thin plate part 143d, the 144d that cross movable body and support; And at bending part 143e, the 144e bending of the end of the first thin plate part 143d, 144d and the second thin plate part 143f, the 144f that extends along movable body 112c.And the first terminal 143a, 144a are at the bending part 143g of the end of the second thin plate part 143f, 144f, 144g bending and to outstanding formation of direction away from movable body 112c.In addition, the first thin plate part 143d, 144d have along support 112b and bending part 143h, the 144h of bending.These bending parts are brought into play function as the rib of the rigidity that improves relaying terminal 134,144.
In Figure 11, when the 111b1 of operating operation portion comes when the arrow B direction applies external force, with the direction strain of movable body 112c to close support 112b.Thus, can dwindle the width W of the slit 112e between the first terminal maintaining part 111b and the second terminal maintaining part 111c.In addition, in variant part 112, be provided with distortion guide part 112a (the distortion guide part that is used for relaying terminal 144 does not illustrate at Figure 11), when making variant part 112 distortion, this distortion guide part 112a follows the distortion of movable body 112c and guides the first thin plate part 143d, the 144d of relaying terminal 143,144 to be out of shape to the first terminal maintaining part 111b one side.This distortion guide part 112a and movable body 112c are integral distortion, therefore can apply power from the side of the first thin plate part 143d, 144d.
In more detail, relaying terminal 143,144 is fixed on the shell main body 133a of cell enclosure 133 with the state that the terminal (not having diagram) of sensor element 132 contacts and conducts with the second terminal 143b, 144b.In addition, the rotary manipulation that carries out when being installed to liquid detecting unit 111 on the container body 105 of the first terminal 143a, the 144a of relaying terminal 143,144 and being electrically connected with circuit board 131 on being fixed in container body 105.
(manufacture method of liquid container)
Comprise in described being connected electrically in that the print cartridge 100 of present embodiment is assembled in the following order.
At first, shown in Figure 13 (A), liquid detecting unit 111 is fitted on the installation portion 123 (referring to Fig. 9 (B)) of container body 105 with the state of vertically holding up.Then, ink bag 107 is placed in the container body 105.At this moment, the connection pin 111a of liquid detecting unit 111 (referring to Figure 12 (B)) links to each other with the ink lead-out member 107a of ink bag 107 after poking diaphragm seal 108.In addition, the container fitting portion 135 of liquid detecting unit 111 (referring to Figure 12 (B)) rotatably is stuck on last concave wall 123a, the 123b (referring to Fig. 9 (B)) that is provided with of spaced walls 105a of container body 105.
Then, rotate chimeric liquid detecting unit 111 to the direction of arrow of Figure 13 (A).As shown in figure 11, at the terminal location of direction of rotation, location division 129 butts of liquid detecting unit 111 and container body 105.
Here, if 111 of liquid detecting units are carried out simple rotary manipulation, then the first terminal 143a, the 144a of relaying terminal 143,144 will clash with the upper end of the sidewall 105d of the detecting unit accommodation section shown in Figure 13 (B).
Therefore, before the first terminal 143a, 144a and sidewall 105d clash, operating portion 111b1 shown in Figure 11 is carried out operation to the pushing of arrow B direction.Thus, make variant part 112 strains, thereby can dwindle the groove width W of slit 112e.
At this moment, follow the distortion of the movable body 112c that takes place when making variant part 112 distortion, the first thin plate part 143d, the 144d of relaying terminal 143,144 is deformed guide part 112a guiding, thereby can make the first terminal 143a, 144a follow movable body 112c reliably.
Therefore, under the situation that can not clash, be further rotated liquid detecting unit 111 and make it arrive above-mentioned rotation terminal location in the upper end of the sidewall 105d of the first terminal 143a, the 144a of relaying terminal 143,144 and the detecting unit accommodation section shown in Figure 13 (B).
As shown in figure 11, at rotation terminal location, location division 129 butts of liquid detecting unit 111 and container body 105.Here, as shown in figure 11, movable body 112c has operating portion 111b1 at a free end that extends from the bottom that links with connecting portion 112d, has the 112f of the portion that is positioned that extends to another free end from the bottom in addition.Portion 112 contacts with location division 129 in case be positioned, and variant part 112 just can not dwindle the distortion of the groove width W of slit 112e.This is because following reason: if the groove width W of slit 112e is dwindled, just must enlarge the groove width of the 112f of portion one side that is positioned, but location division 129 stops the expansion of the groove width of the described 112f of portion one side that is positioned.Thus, prevented that at the rotation terminal location variant part 112 from deforming.
In addition, at this rotation terminal location, go back confined liquid detecting unit 111 and rotate to the origin-location.This is because the operating portion 111b1 rotation that is sandwiched in bearing surface 105e and its top on the bottom surface that is arranged at container body 105 limits cause between the muscle 105f as shown in Figure 15.In this position, the rotation terminal location is prescribed, simultaneously as long as inoperation operating portion 111b1 can also prevent to rotate back on the origin-location so.The 111b1 of operating operation portion in the process of liquid detecting unit 111 rotations is not so that liquid detecting unit 111 conflicts with rotation restriction muscle 105f.
When the rotation extreme positions is removed operating portion 111b1 externally applied forces, the first terminal 143a, 144a return on the anterior position with movable body 112c, and shown in Figure 13 (B), are electrically connected with the fixed contact 131d of circuit board 131c.At this moment, shown in Figure 14 (B), inserted as the first terminal maintaining part 111b of jut and to lead in the 143a1 of slotted hole portion, 144a1, the first terminal 143a, the 144a with the 143a1 of this slotted hole portion, 144a1 forwards, promptly the direction of arrow to Figure 14 (B) is highlighted biasing.Thus, the rotation terminal location in that the distortion of variant part 112 is prevented from also can flexibly be pressed against the first terminal 143a, 144a on the circuit board 131.Can guarantee the strong electrical connections of ability such as anti-vibration thus.
When the box installation portion of tape deck is installed print cartridge 100, the ink supply pin that disposes on the box installation portion is poked diaphragm seal 157 and is inserted liquid and derive in the parts 109.Thus, can be from print cartridge 100 to record head supply ink.
(mounting structure of circuit board)
Figure 18 is the plane of the circuit board 131 shown in Fig. 8 and Fig. 9 (A).Figure 18 is the figure that circuit board 131 is watched from a surperficial side, is formed with a plurality of contact 131a that are connected with the splicing ear (connector) of box installation portion one side on its surperficial 131A.In addition, as shown in phantom in Figure 18, on the 131B of the back side of circuit board 131, be formed with memory element 131c and fixed contact 131d, this memory element 131c is used for the information of use history of ink surplus or box etc., and this fixed contact 131d is connected with sensor element 132 via relaying terminal 143,144.
In addition, the porose 131e of a distolateral formation on for example length direction of circuit board 131 is at another distolateral recess 131f that is formed with.In addition, also be formed with notch (broadly being deformed part) 131g on circuit board 131,131g will be described hereinafter to this notch.
Figure 19 is the comparative example that the state on the sidewall 105d that the circuit board 131 ' that will not have the notch 131g in the circuit board 131 shown in Figure 180 is installed in container body 105 is shown.As shown in figure 19, circuit board 131 ' is to expose its surperficial 131A and its back side state of 131B in container body 105 is installed on the sidewall 105d of container body 105.
Figure 19 shows the 200B of hot riveting portion, 202B does not have the fully state of formation.Defective under this state is as follows: when as above-mentioned when liquid detecting unit 111 has been installed, the first terminal 143a, 144a contact with the fixed contact 131d of the back side 131B of circuit board 131 ' in the mode to the pushing of arrow directions X.At this moment, in Figure 19, owing to be subjected to the pushing force of the first terminal 143a, 144a, the back side 131B of circuit board 131 ' separates with the opposite face of sidewall 105d, thereby forms gap 204.That is,, the 200B of hot riveting portion produced gap 204 owing to can not forming enough big size.
The 200B of hot riveting portion can not form enough big size will mean that the 200B of hot riveting portion does not have enough strong intensity.If the weak strength of the 200B of hot riveting portion, then owing to the pushing force of the first terminal 143a, 144a, there is the danger that breaks away from from first fastener 200 in circuit board 131 '.
Figure 20 shows the installment state of the circuit board 131 that comprises notch 131g shown in Figure 180, even if this figure also can prevent the description of the present embodiment figure that circuit board 131 comes off under the situation of the inadequate hot riveting 200B of portion of hot riveting as shown in figure 18.
As shown in figure 20, when by the first terminal 143a, 144a when the arrow directions X has applied pushing force, the weak notch 131g of flexural strength bends along diagram Y direction among the circuit board 131.Become big by this flexural deformation, absorb pushing force, can reduce the power that the 200B of hot riveting portion (and the 202B of hot riveting portion) is born thus from the first terminal 143a, 144a.Thereby, can prevent the fault that circuit board 131 comes off from the inadequate hot riveting 200B of portion of hot riveting.
Such effect need the position between the end of fixed contact 131d and second fastener, 202 1 sides on the direction on a limit of circuit board 131 be provided with the notch 131g of the function that plays deformed part.In addition, in Figure 18, kept hole 131e and these two parts of recess 131f, but, also can set up the number of fastener with hot riveting portion according to the aggravate stress of the first terminal 143a, 144a with first, second fastener 200,202.
Structure shown in Figure 20 also has following effect.When the box installation portion of tape deck is installed print cartridge 100, can improve the relation between device side connector 210 and the circuit board 131.As shown in figure 20, when circuit board 131 causes flexural deformation as shown in the figure like that, the distortion that descends towards two ends as the summit with deformed part (notch) 131g will take place.Therefore, with the state of Figure 19 (owing to there is not notch 131g, circuit board 131 is difficult to distortion) compare, on the length direction of circuit board 131, position than notch 131g, with the position of the end of the relative side of the 200B of hot riveting portion, circuit board 131 more descends to arrow Z direction, and circuit board 131 in the position of notch 131g and the part run-off the straight between the substrate end.When the box installation portion of tape deck is installed print cartridge 100, print cartridge 100 moves to the arrow P direction.Thus, device side connector 210 contacts with contact 131a on the surperficial 131A that is formed on circuit board 131.In this process, circuit board 131 contacts with device side connector 210 at a certain angle, and then, circuit board 131 is mounted under the situation of slipping with connector 210.In the starting stage of this process, when the insertion front end of circuit board 131 had just begun to contact with device side connector 210, the insertion front end guidance device side connector 210 of the circuit board 131 of inclination slipped itself and circuit board 131.Thus, the bight of the insertion front end of circuit board 131 can not collided with device side connector 210 and breakage is taken place, and the fault that circuit board 131 self comes off from the 200B of hot riveting portion perhaps can not take place yet.
(decomposition method of liquid container)
The decomposition method of print cartridge 100, especially, when from container body 105 dismounting liquid detecting units 111, the 111b1 of operating operation portion makes variant part 112 distortion, thereby dwindles the groove width W of slit 112e shown in Figure 11.After this, on one side the operating operation 111b1 of portion, one side rotating liquid detecting unit 111.Thus, can limit under the afoul situation of muscle 105f, make liquid detecting unit 111 rotate back into the state of Figure 13 (A) in upper end that does not make the sidewall 105d shown in operating portion 111b1 and Figure 13 (B) and rotation shown in Figure 15.So, can not dismantle liquid detecting unit 111 with damaging, thereby can utilize liquid detecting unit 111 again.
